Title: Method for cooling reaction tube
Inventor: MARUYAMA KENJI
IPC: H01L21/365
Filed: 1988-08-19
Abstract: PURPOSE:To reduce pressure and flow rate of a cooling medium and miniaturize a reaction tube by admitting a fine particulate substance of the cooling medium, mixed and dispersed in a carrier gas into an outer tube of a reaction tube having a double-pipe structure and cooling the inner tube with heat of evaporation of the fine particulate substance. CONSTITUTION:An ultrasonic vibrator 13 is provided in the bottom of a vessel 12 containing water 11, which is then converted into fine droplets (11A) (having about 0.1mu diameter) by vibration of the vibrator 13 to fly out. The droplets (11A) are introduced into an outer tube 6 of a reaction tube 7, having a double- pipe structure and consisting of the outer tube 6 and an inner tube 1 using nitrogen gas as a carrier gas to cool the tube wall of the inner tube 1 with heat of evaporation of the droplets (11A). In the process, the amount of the droplets (11A) is about 0.1g based on 2l/min inflow gas rate of the nitrogen gas. Thereby, the reaction tube 7 can be miniaturized without requiring a large amount of the water 11 and applying a high pressure to the outer tube 6.

IPC: B65H3/52
Filed: 1981-12-21
Abstract: PURPOSE:To stabilize the separation performance of a pressure-contact-type sheet feeder for a copying machine despite the thickness of a sheet, by providing a paper feed roller and a separating roller in a separating section so that the separating roller is rotated in a sheet backing direction and put in pressure contact with the sheet on the feed roller and by driving one of these rollers. CONSTITUTION:A second sheet feed roller 3 is rotated through a sprocket 11 and a roller shaft 6 in a sheet feeding direction as shown by an arrow. A separating roller 4 is rotated through drive gears 12, 13 and a roller shaft 7 in a sheet backing direction and pushed onto the feed roller 3 through a swing frame 8, a spring 10 and a roller shaft 7. A sheet conveyed from a stacking section is pinched between the feed roller 3 and the separating roller 4. When overlapped sheets are conveyed, their bottom is moved back by the separating roller being rotated in the backing direction, to separate the first sheet from the other. Separation performance stable for a wide range of sheet thickness is thus attained by a spring-urging force and a swing mechanism.

IPC: H01L21/66
Filed: 1981-12-24
Abstract: PURPOSE:To measure channel concentration of the semiconductor at the vertical JFET by a method wherein the voltage value of a reverse voltage between gates and a drain to generate a rapid variation of electrostatic capacity and channel size between the gates obtained according to a grinding means are used. CONSTITUTION:The P<+> type layers 9 are buried in an N type Si substrate 1 having concentration ND preventing mutual contact by N type compensation layers 7, 7', and an N type epitaxial layer having concentration NE is stacked thereon. The N type of the layers 7, 7' is canceled by B ions diffused from the P<+> type layers 9 according to thermal diffusion, and concentration of the channel 5' is reduced. When reverse voltages V are applied between the drain 3 and the cylindrical gates 9, before (A1) and after (A3) generation of the pinch off condition of depletion layers 6, capacity C varies rapidly at V=qNDb<2>/2epsilon. At this time, V=1 and epsilon, q are known. Then the element is ground at an angle and is colored, and when channel size is measured, channel size becomes to 2b. When b is decided as b 3mu, concentration ND of the channel can be calculated from the above-mentioned expression.

Title: Recognition system for on-line handwritten character
Inventor: OOTA GICHU
IPC: G06K9/62
Filed: 1984-10-05
Abstract: PURPOSE:To simplify a character recognition system by approximating each stroke at many points for characters like HIRAGANA (Japanese syllabary) including curve components and securing the resemblance with a standard character approximated at a point where the strokes are thinned among those standard characters approximat ed at the same point. CONSTITUTION:The input character sent from a character information input part undergoes the conversion of coordinates so that the centroid point is coincident with an original point as well as the normalization so as to secure a fixed distance between the centroid point and each stroke point. Thus the number 201 of strokes is detected. Each stroke is approximated at a point 2N-1 including both start and end points at an approximate point extracting part 3. Then an inter-pattern distance calculating part 4 obtains the distance between approximate points for a thinned point N and a pattern stored in a standard pattern memory part 7. For the result of this calculation, a minimum distance detecting part 5 detects the minimum and the next minimum values. Then the part 4 obtains a ratio between both values and delivers a code corresponding to a category of the stroke showing the minimum value when said ratio is larger than a certain threshold value through a switch part 10. Then the correction is carried out based on a category code for discrimination from an approximate character via a resemblance table 8.
